SEAT-FASTEN EFL` SPECIFICATION forming part of Letters latent No.395,180, dated December 25, 1888.

Application filed May 10, 1888. Serial No. 273,403. (No model.)

To all whom it may concern,.-

Ee it known that I, MICHAEL D. SCHALER, a citizen of the United States,residing at Lowell, in the county of Oneida and State of New York, haveinvented a new and useful Improvement in Seat-Fasteners,,ot which thefollowing is a specification.

The invention relates to improvements in seat-fasteners, beingespecially adapted 'for the seats of wagons; and it consists in theconstruction and novel combination of parts hereinafter described,illustrated in the accompanying drawings, and pointed out in the claimhereto appeinled.

Figure l of the drawings represents a perspective View of a wagon-seathaving a fastener embodying the invention attached, the saine beinglocked. Fig. il represents a similar view with the fastener unlocked.

Referring to the drawings by letter, A designates a seat-rail, uponwhich rests the rider B, the lower edge of which is supported upon theupper edge of the rail and bears on the outside against the verticalflange a, rising from said rail. The seat C is secured to the top of therider by any ordinary means.

I) is a rectai'igular plate bolted or otherwise securely attached to therear surface of the riser, and provided adjacent to its lowerl edge withthe outstanding perforated cam-lugs E, having the upper inclined camsurface or end, e.

F is a rod passing' through the perforation of said lug, having itsupper end screwthreaded and its lower end,f, bent at right angles, inord er to pass under and rest against the lower edge ot' the seat-rail.The said rod has on its threaded end the nut f and washer f2 and passesthrough the perforated camboss G of the lever-arm g, which boss has thelower cani end, g', inclined at an equal angle to that of the cam end e.The arm g has at its tree end a short outward projection for ease inturning the arm on the rod F. IVhen the inclined cani ends rest flatupon each other, their inclines being in the saine direction and thewhole of their meeting surfaces touching, the rectangularly-bent ends fof the rod F may be turned under the Seat-rail withont binding1 thereon.NVhen the armis, however,n turned in the opposite direction, theinclination of the cam end y is reversed, andit rises on the cam end e,causing the end of the rod to bind on the seat-rail and hold the riserthereto.

H is a button pivoted at a proper point upon the plate D in position tobe turned 011 the lever-arm when the riser is locked upon the seat-rail.The innerfedge, 7L, of the engagingpoint of the button is rounded, sothat it will hold the lever-arm more tightly to the plate B the more itis turned inward on said arin.

h is a pin standing' outward from said plate in position to prevent thebutton froni being turned up too 'far off the arm g.

It is evident thatby the described means the riser and attached seat mayquickly and easily be secured to the seatfrail at any desired pointthereon. If the end f does not hold tightly enough on the lower edge ofthe seat-rail, the nut j" should be turned up till said end binds.

Having described niy invention, I claim- In a seat-fastener, the plateD, provided With a lug, E, having an upper cani-surface, the boss G,provided with a lower cam-surface resting on the lug E, and having' anarni, g, and the rod F, passing through the central registering openingsin the lug and boss, provided at its lower end with a bend, f, andengaged at its upper end by a nut, in combination with the button H,provided with a rounded lower end adapted to bear on the arm g,substantially as and for the purpose specified. Y

In testimony that I claim the foregoing as iny own I have hereto affixedmy signature in presence of two witnesses.

MICHAEL D. SCHALER.
